One of the
most reviled and misunderstood pests known to man is the bed bug (Cimex
lectularius). How many of us dozed off to sleep at night as children
with the words of our parents in our ears ‘sleep tight and
don’t let the bed bugs bite’?
Bed bugs possibly started to feed on man at about the time we moved
into caves, the ‘bat bugs’ Cimex pilosellus and
Cimex pipistrella primarily feed on bats and it is probable that bat
feeding species of bug evolved to dine on human blood when our
ancesters started dwelling in bat infested caves.
Until the invention of DDT in the early 20th century bed bugs were
common unwelcome guests in a lot of poor quality housing.
The later part of the 20th century has seen pest control companies
dealing with very few bed bug calls indeed, their presence being
largely restricted to cheap holiday camps and student lodging etc.
Many people confuse dust mites, which are not visible to the unaided
eye, with bed bugs which certainly are.
Adult bedbugs are reddy-brown, about a quarter of an inch in size and
very swollen after a feed of human blood.
They experience an incomplete metamorphosis which means that the young
are just smaller versions of the adult, they do not have a pupal stage
like fleas or a fly
Bed
bugs regularly feed on
human blood every 7 – 10 days, emerging in the hours before
dawn and
finding their prey by detecting the exhaled CO2 from our breathing and
when nearing in on their target, infra red body heat.
In the absence of
a regular human host to feed on they can |remain dormant for
periods of up to 18 months.
Indications
of a bed bug problem are spots of blood on bed sheets and on the
underside of mattresses and some people can react badly to their bites.
The
early 21st century has seen bed bug numbers
increase across the planet, the easy availability of world travel and
economic migration have both been blamed for the resurgence.
What
is sure is that they are now making a real return not only in low
quality homes but high class hotels, schools and even hospitals.
One London
borough reported a doubling of bed bug problems every single year from
1995 – 2001.

Cheshire Bed Bugs
A single night
away in an infested hotel is all it takes, they hitch a ride in your
suitcases or bags. Pest control firms are also now reporting instances
of transport related bed bug infestations on tubes, trains and buses so
a simple ride to town on an infested bus or train can be sufficient to
spread the infestation to your home.
They are an
expensive pest to eradictate as contrary to popular mythology they do
not just live in beds. They hide any nook and cranny conveniently close
to a sleeping human being, beds, electrical sockets, televisions,
bed-side bed side telephones etc and dealing with them is both
difficult and time consuming. They have even been found living beneath
the toe-nails of infirm people and in the folds of flesh on heavily
over-weight people.
They are not a
pest that can be tackled by an amateur and a professional will almost
certainly be required.
